!Various measurement processes

!Rapid

!Independent of viscosity

!Free from losses

!Plenty of measurement ranges

!Analogue output signal

!M12 plug-in connection

!24 VDC

The SensoControl® fl ow sensors are used for the exact

determination of volume fl ows in hydraulic equipment

(eg test and inspection stands).

The sensors deliver an output signal proportional to the

volume fl ow for further processing in an electronic system

and are compatible with the usual proven industrial stan-

dards.

!M12 plug-in connection

!24 VDC

!0/4…20 mA

The volume fl ow can be easily displayed in combination

with the SCE-020 built-in measuring instrument.

To meet a multitude of application requirements there are

three different measurement principles available:

!Gear counter SCVF

!Turbine SCFT

!Spring/piston SCQ

Volume fl ow sensors are used in control, regulation and

monitoring systems, where analogue signals to capture

volume fl ow are needed.

2.1 SCQ Flow meter

!Measurement principle: spring/piston

!Response time ≤ 2 ms

!Measurement in both directions

!Wide viscosity range

!Compact construction

!Pressure resistant up to 420 bar

FunctionThe piston (K) is moved by fl ow from A to B or B to A. In idle

mode, the spring (F) and piston (K) are in equilibrium. The

change in travel (S) is proportional to the volume fl ow and is

converted into a measured value by the built-in electronics.

If the direction of fl ow changes (B to A), fl ow directions can

be displayed (eg -45.8 l/min). The reaction time of the piston

movement is smaller than 0.002 s.

Application The rapid capture of the fl ow quantity is of great importance

in the fi eld of high-pressure hydraulics.

Mounting with the connection block permits a combined

measurement of p, T and Q. With the in-line adaptor for

tube or hose mounting, rapid installation of the SCQ into the

hydraulics is achieved. The rugged construction enables use

to continue even under extreme conditions, as for example,

high load reversals or pressure increase speeds.

If highly dynamic volume fl ow changes are to be captured,

the SCQ is the ideal solution. Rapid load changes, which

can cause damage to valves or pumps, can be safely

captured. Because of its unique measuring process, the

SCQ is also in a position to capture volume fl ows in both

directions.

2.2 Messturbine SCFT

!Measurement principle: turbine

!Response speed 50 ms

!Measurement ranges from 1 to 800 l/min

!Low fl ow resistance

!Nominal pressure to 480 bar

!Suitable for reverse operation

!Built-in pressure and temperature

connections

Function

The turbine wheel is driven by the oil fl ow and starts to turn.

The frequencies which this produces are processed by

the digital electronics and the infl uences of interfering fl ow

effects are compensated. Thanks to low fl ow resistance

QR, the hydraulic circuit is operated with low losses

Because of the special vane design, reverse operation is

also possible, ie. the turbine can be operated in both direc-

tions.

The turbine is equipped with an EMA-3 screw coupling for

measurement of pressure. Oil temperatures can be mea-

sured by inserting an SCT-150 directly into the turbine oil

stream. In this way all the important measurement param-

eters are available at one installation location.

Application

If the volume fl ow is to be captured without loss over wide

volume ranges (up to 800 l/min), then the SCFT is the ideal

solution.

2.3 SCVF Volume counter

!Measurement principle:

gearwheel volume counter

!8 measurement ranges

from 0.01…2 to 1.0…300 l/min

!Measurement accuracy ± 0,5 % FS

!Pressure resistant to 400 bar

!High viscosity range

!Low noise

!Exact fl ow measurement

over wide viscosity range

!Flexible use for various media

Gearwheel counter for high accuracy fl ow measurement in hydraulic equipment

FunctionThe SCVF gearwheel counter works as a volume fl ow

counter. A very precisely machined pair of gears is driven

by the fl uid fl ow. The SCVF works in a wide range of viscosi-

ties. Various seals permit a variety of applications.

Applications Thanks to this wide range of viscosities, all fl uids which can

be pumped and have a certain degree of lubricating ability

can be measured:

!!Brake fl uid (EPDM seals)

!!Skydrol

!!Mineral oils

!!Hydraulic oils

!!Greases

If exact fl ow measurements over a wide range of viscosities

are to be captured, the SCVF is the ideal solution.
